Wall Street may dislike uncertainty, but investors worried that a divided Congress under President Donald Trump will trigger a market collapse can take some comfort from history.

The record suggests political gridlock may restrain returns, yet it has rarely doomed stocks.

Since the late 1890s, roughly three quarters of presidential terms have produced stock market gains. Annualized returns for the Dow Jones Industrial Average, S&P 500, and Nasdaq Composite under Trump have also exceeded those recorded during many other presidencies.

Washington cannot claim all the credit, of course. Artificial intelligence, corporate earnings, technological innovation, and investor enthusiasm have powered much of the advance, although tax and spending policies can still influence business investment and stock valuations.

That makes the Nov. 3 midterm elections an important test. Republicans began the first two years of Trump’s second term with control of the White House, Senate, and House of Representatives, giving the administration a relatively clear path for its agenda.

History suggests that advantage is vulnerable. In 18 of the 20 midterm elections held since World War II, the president’s party lost seats in the House, while Senate losses have also been common, though generally less severe.

Republicans currently hold 53 of the Senate’s 100 seats and a razor thin 218 seat majority in the 435 member House. Prediction markets indicate that neither majority can be treated as secure heading into Election Day.

As of early Sept. 1, Polymarket traders assigned a 51 percent probability to Democrats capturing both chambers. Another 36 percent expected Democrats to win the House while Republicans retained the Senate, and only about one eighth anticipated continued Republican control of Congress.

Unified government matters because it makes large legislative packages easier to pass.

During Trump’s first term, Republicans approved the Tax Cuts and Jobs Act, which permanently reduced the highest corporate income tax rate from 35 percent to 21 percent and lowered personal tax rates for many workers.

Those corporate tax reductions helped support profits and record share repurchases. During the first year of Trump’s second term, Republican control also helped pass the “Big, Beautiful Bill,” which made personal tax bracket reductions permanent and created temporary tax benefits covering 2025 through 2028.

Democratic control of either chamber would sharply reduce the odds of another sweeping tax or spending package.

It could also produce harder debt ceiling negotiations and increase the risk of federal shutdowns, bringing Washington’s familiar fiscal brinkmanship back into the market conversation.

Yet divided government has not historically been a disaster for investors. Mike Patton, president of Integrity Wealth Management and a Forbes columnist, found that the Dow generated an average annual return of 12.9 percent from 1946 through 2020 when Democrats and Republicans split control of Congress.

The results become less impressive when the party holding the presidency is considered. Retirement Researcher found that the S&P 500 returned an average of 14.52 percent during the 13 years from 1926 through 2023 when Republicans controlled the presidency and both congressional chambers.

By comparison, the S&P 500 delivered an average annual return of 7.33 percent across the 34 years when a Republican president faced a divided government.

That is a meaningful slowdown, but it is still a solidly positive return rather than evidence of an approaching market crash.

Stocks can certainly suffer corrections regardless of who runs Congress. Elevated valuations, rapidly expanding margin debt, stubborn inflation, interest rate changes, geopolitical conflict, and weakening earnings can all spark sudden declines, but congressional composition is rarely the sole cause of an elevator style selloff.

The broader historical record remains encouraging across nearly every political arrangement. Whether Republicans retain unified control, Democrats capture both chambers, or the parties divide Congress, average long term returns for the Dow and S&P 500 have remained positive.

Crestmont Research offers an even stronger case for patience. Its analysis of 107 rolling 20 year periods for the S&P 500 since 1900 found that every period generated a positive annualized total return when dividends were included.

In practical terms, a hypothetical investor who purchased an S&P 500 index fund equivalent between 1900 and 2006 and held it for 20 years made money in every measured period. Political control changed repeatedly, but innovation, productivity, and corporate earnings ultimately overwhelmed the noise from Washington.

A split Congress could limit Trump’s legislative options and produce more modest market gains than unified Republican control has historically delivered.

Still, history offers little reason to expect political gridlock alone to cause stocks to plunge, especially for investors willing to look beyond one election cycle.
